KitchenAid Dishwasher F9 E1 Error: Drain Timeout Error
What Does KitchenAid Dishwasher Error Code F9 E1 Mean? The F9 E1 error code on a KitchenAid dishwasher with an alphanumeric display signals a drain timeout. The control board commands the drain pump at the end of each wash and rinse stage and monitors the water level drop. If the tub does not drain within […]
Quick Assessment
Answer to continue safely
Is it safe to keep using?
No. Stagnant water in the tub becomes unsanitary within hours and prevents the next cycle from running correctly. Do not use the dishwasher until drainage is restored.
Can I reset the code?
Yes. Holding Cancel for three seconds initiates a drain attempt and clears the F9 E1 code if the drain succeeds. If the drain path is clear, the code will not return on the next cycle. A pump that is physically impaired will return F9 E1 on every cycle.
When to stop immediately?
Stop if you notice: F9 E1 appears on every cycle after filter cleaning and drain hose check, Drain pump makes no sound when commanded to run.
Symptoms You May Notice
Water sits in the bottom of the tub at the end of every cycle
Regardless of which wash cycle is selected, the dishwasher always ends with two to four inches of water in the sump that the pump never removed.
F9 E1 shows on the display between cycle stages
On KDTM and KDTE models, F9 E1 appears on the alphanumeric display during the transition between wash and rinse or between rinse and dry.
Drain pump hums briefly then stops without clearing the tub
The pump motor activates — audible as a low hum — runs for five to ten seconds, then shuts off before the tub is drained, repeating this pattern two or three times before the fault is logged.
Possible Causes
Clogged filter or sump restricting drain pump suction
The filter screens are so blocked with food debris that the pump cannot draw enough water to drain within the timeout period.
DIY PossibleDrain hose clog, kink, or missing high-loop
The drain hose has a blockage, a sharp kink, or does not have the required high-loop, allowing sink water to siphon back into the tub and stall the drain.
DIY PossibleFailed or partially seized drain pump
The drain pump impeller is restricted by a foreign object (glass shard, bone chip, pit) or the pump motor windings have partially burned out, reducing pumping power below the drain threshold.
Requires ProfessionalSafe Checks You Can Do
-
1
Clean the filter and check for debris in the sump
Remove the lower rack. Unlock and remove the cylindrical filter and flat mesh screen. Rinse both thoroughly. With filters out, look into the sump cavity with a flashlight for any glass, pits, or small debris that could be restricting the pump inlet.
Even a small chip of bone or a grape pit can partially block the drain pump inlet enough to slow drainage below the threshold that triggers F9 E1.
Tools required -
2
Inspect and clear the drain hose
Open the under-sink cabinet and follow the drain hose to the sink drain or disposal connection. Look for kinks, cracks, or a hose that drops below the sink drain level without a high loop. If connected to a garbage disposal, confirm the disposal knockout plug has been removed.
A new disposal installation is a very common cause of F9 E1 — the plastic knockout plug inside the disposal drain inlet is frequently left in place, blocking dishwasher drainage entirely.
When to Call a Professional
Contact a qualified technician if:
- Pump impeller cannot be turned by hand (requires removing lower sump panel)
- Pump motor reads open or shorted winding on a multimeter
- Drain hose is clear and high-looped but drainage still does not complete
